[ILUG] Question on an encryption system (using OSS)

I'm thinking of putting together an encryption system using some sort of
either symmetric or public key encryption and I wanted to get some
advice from the list...
Basically, what I want to do is as follows:
1. I encrypt a file
2. I make this file available via a P2P system like bit torrent.
3. When someone downloads the file, in order to unencrypt it, they have to
get a key from me.
4. Since I make it available on P2P, multiple people might download it. Each
person that wants to read it
has to get a different key so that each key is unique to that person.
I'm guessing a public key encryption scheme works best here. I'm thinking of
using GPG to actually perform the encryption and
generate the keys.
Is what I want to do basically sound? I.e. am I missing something obvious
here security-weakness wise?
